LOOM-SHUTTLE.

SPECIFICATION forming pari: of Letters Patent N0. 539,238, dated May*14, 1895.

Application filed May l, 1893. Serial No. 472,512- (No model.)

To all whom it may concern! Be it known that I, JAMES C. SERGEsoN, acitizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Loom-Shuttles, which improvement is fully set forth inthe following speciiication and accompanying drawings.

My invention consists of a shuttle having a catch plate for engagementwith the bobbin, formed with an angular `and tapering opening, and ascrew which is provided with an angular and tapering head, said platehaving on its inner face aboss which is continuous' of the wall thereof,and'having its opening coinciding with that of the plate, whereby thescrew is prevented from rotating itself loose, it having a broad bearingon said plate, and its hold ou the body is firm and.secure without theemployment of a nut for such purpose.

Figure l represents a perspective View of the inner face of the bobbincatch-plate of a shuttle embodyingmy invention. Fig. 2 represents alongitudinal section of a portion of the shuttle embodying my invention.

Similar letters of reference indicate corresponding parts in the twofigures.

Referring to the drawings:` Aldesignates the body of a shuttle whichexceptingtheY features of my invention, is of ordinary construction.

B designates the catch or catch plate which is connected with the part Bof the body of the shuttle, and has at one end a nose C for engagementwith an annular groove on the head of the bobbin D, whereby the latteris held in operative position, the other end of said catch plate beingpressed outwardly by the spring E, which bears against said catch, andthe opposite spindle-holding. plate F on the heel ends' thereof, saidplate VE exerting pressure on the pivoted head G of the spindle.

The plate F is adapted to bear upon one face of the spindle head to holdthe spindle in proper alignment in the shuttle, and upon another face ofthe head when the spindle is raised to hold it in position to change thebobbin. l

H designates the bolt or screw which con nects the catch plate with thebody of the Shuttle, the same having an angular head J,

the latter freely occupying a counter-sunk opening K in said plate,whereby the latter is permitted to rock or oscillate lightly on saidhead as the bobbin engageswith and disengages from the nose C. The wallsof the opening K are extended inwardly, forming the boss L, whoseopening is continuous of said opening J, and whose wall is both angular4and tapering, like a truncated pyramid. The head of the screw coincidesin its angle and taper with the walls of said opening and boss, andoccupies the openings of both the plate and boss, whereby it has anincreased holding surface on the catch plate, and the material of saidcatch around said opening K is vastly p 'strengthened at a place wherethe plate is subjected to considerable strain, the screw being alsoprevented from rotating in reverse direction, as its head is controlledby the wall of the opening K and the boss L.

When the plate B is forced inwardly against the spring E, the head J ofthe screw H is uncovered, when the same may be engaged by a suitable keyand rotated to remove the screw H, and consequently said plate, the sameprovision existing when saidplate is to be restored to position, thehead being caused to register with the opening K, the plate then beinglet go, whereby the wall of said opening and the boss L again embracethe head of the screw. Theplate E has a boss similar to that of theplate'B, and the screw E is formed with an angular-head similar to thescrew H.

'Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

Ashuttle body provided with the bobbincatch and spindle-holding plates,each formed with a boss having an opening of angular and tapering Shape,secu ring screws having angular and tapering heads which occupy .thebosses of said plates and on which'said plates are adapted to oscillate,and a single spring bearing against the heel ends of said plates, theparts being combined substantially as described.

JAMES C. SERGESON.
